operator for adjusting them on verticali axes-as, for example, bypressure applied to foot levers extending laterally from the spindlesupon which the supporting wheels are mounted-in the guiding of theimplement during its travel.

One of the most important purposes .of

the invention is to provide an implement of the kind stated having animproved correlation of parts for enabling the earth-working elements tobe shifted laterally so as to dodge a stalk of corn set out of line withthe rest of the row, or follow a crooked row or avoid digging up thecrop in barring ofl", without changing their angle relatively to thegeneral direction of the row. In accordance with this purpose of theinvention I have provided an implement characterized by its inclusion ofangularly yadjustable supporting wheels connected with a pivoted pole bya means which cordinates the movements thereof, the wheels furtherhaving connection with the rear ends of the members which carry theearth working elements and the pole having connection with the forwardends of said members, the correlation of the parts being such that; whenthe wheels are adjusted angularly the pole is turned pivotally and thebeams are moved bodily laterally in parallelism with each other.

It will be apparent that the characteristics herein referred to may bemore or less successfully embodied in various ways, but as it is anadditional purpose of the present invention to provide the mostpracticable embodiment thereof, I have deviseda construction andcombination of parts whichis believed tocarry the leading purpose of theinvention into practice in the best manner and this particularconstruction and combination of parts forms-additionally an importantpart of the present invention. f

Moreover, the present invention aims to provide improvements in respect(l) to the connection' of the forward ends of the members Ywhich carrythe earth-working elements with the pivotedipole and (2) to the mea-nsfor adjusting the rear ends of said members and holding them in adjustedposition.

The foregoing purposes, and others which `will fully appear to thosefamiliar with this class of implements from the hereinafter .descriptionof the preferred embodiment of the invention, are fully secured by theconstruction illustrated in the accompanying drawings, wherein likecharacters of reference denote corresponding parts in the several views.Y

In said drawings: Figure lis a plan view of a cultivator embodying thepresent improvements; Fig. 2 is a side elevation ofthe same with thenearer wheel removed; Fig. 3 is a rear end elevation of the implementwith parts broken away to disclose parts which otherwise would beconcealed; Fig.

stood at' the. outset that this construction merely exemplifies the atpresent preferred embodimen'ti of the invention and that changes may bemade and the invention otherwise and variously embodied withoutdeparting from its spirit or the scope of the subjoined claims.

The frame of the implement preferably comprises a transverse member Aand longitudinal members A and A2, the longitudinal members having theirrear ends suitably connected to the member A near the opposite `ends ofthe latter and extending thence convergently toY a housing'B. Thetransverse j member A preferably includes two parallel spaced flatvstrips Q0, 20.

A3 designates the seat for supporting the driver of the implement. Thisseat is suitably connected with the frame of the implement. It ispreferably held against lateral pivotal movement as it does not form anelement of the means for changing the direction of travel of theimplement. For holding it against lateral pivotal movement l preferablyemploy a block or casting A'L having a recess a4 to receive the seatarms The block or casting A4 also serves to stiffen the center of themember, being arranged between and secured to the strips 20, as shown.

C, C designate brackets which are arranged at opposite ends of thetransverse member A and are suitably connected to the latter and dependtherefrom. These brackets provide bearings in which the verticalportions of the axles 22 are pivotally mounted and also serve to stiffenthe ends of the transverse member A. The axles 22, hereinafter termedaxle spindles, have outwardly extending' ends upon which the supportingwheels D are rotatably mounted. t will be noted that the supportingwheels are adjusted angularly upon vertical axes when the axle spindlesare turned in their bearings.

rlhe preferred construction of one of the brackets C is shown in detailin Fig. 5, upon reference to which ligure it will be noted that thebracket comprises'a sleeve 23 through which the spindle 22 extends, alaterally expanded upper end 24 having' channels 25 in its oppositesides and stiffening flanges or webs 26 and 27 arranged at oppositesides of the sleeve 23 and extending to the upper end 2l. The channels25 respectively receive the ends of the strips 20, the latter beingclosely fitted therein. erably has its upper end 24 provided with acut-away section which also extends through the flange 27, to lightenit. Its lower end is suitably provided with an ear 28. The other bracketis of like construction and need not be particularly set forth.

Each member A, A2 of the frame has an outwardly extending rear end 29which lies upon the adjacent strip 20, and near its rear end each memberhas a depending bracket 30 which is connected by a sti'lfening rod 3lwith the ear 28 on the adjacent bracket C. See Fig. 5.

E designates a transverse member which is slidably mounted andpreferably is arranged in advance of and lbelow the hori- Zontal planeof the frame member A. This member E has its opposite ends suitablyconnected to the axle spindles 22, so as to transmit axial movement fromone spindle to the other. The means for connecting the ends of themember E with the axle spindles, respectively, preferably compriseprojections 33 from the axle spindles, projections 34 from the ends ofthe transverse members and arms 35 fixed to the projections 33 andpivoted to the projections 34. See Fig. 4l.

` The member E should be guided in its movements transversely of theimplement and for so guiding it the brackets 30 pref- The bracketpreferably are utilized, the said brackets having their forward facesformed with channels 36 which receive the transverse member, see Fig. 5,in which one of the brackets 30 is shown in detail and the transversemember is indicated in dotted outline.

Each axle spindle 22 is provided with suitable means, such as a footlever F, so arranged that it may be actuated conveniently by theoperator, who is seated on the seat A3. It will be noted that wheneither foot lever is pressed forward the axle spindle 22 connectedthereto will be turned and the transverse slidable member E willcorrespondingly turn the other axle spindle. The transverse member ispivoted to the rear end of a pole G, at 37. This pole extends looselythrough the housing B and is pivoted to the latter, so as to turn upon avertical axis therein, at 38. Accordingly, it will be noted that whenthe transverse slidable element lE receives motion from either -axlespindle 22 it not only transmits axial movement to the otherv axlespindle 22 but further moves the rear ends of the pole Gr pivotally. Themember E thus cordinates the movements of the axle spindles and pivotpole. y

H, H designate members which extend longitudinally of the implement andcarry the gangs of soil working elements H, H. AThese memberswhich arehereinafter called beamS-may be of any suitable construction. The soilworking elements also may be of any suitable kind, disks beingpreferred. The soil working elements may be connected to the beams inany suitable way, but I prefer to arrange them in gangs and to connecteach gang to its beam in a manner which permits independent adjustmentof the angular relation of the gangs to each other and allows the gangsto be held in their selected positions of adjustment. As lgangs thusmounted are common in the art it is not believed to be necessaryparticularly to describe or illustrate the same herein.

The transverse member E is provided near its end with depending arms 39and these arms extend through boxes Ll0 which are suitably securedto thebeams H at a place considerably rearward of the forward ends of thelatter. Hence, slidable movement of the member F transversely of theimplement will correspondingly move the rear ends of the beams H, H.

Means are provided for connecting the forward ends of the beams H, Hwith the pole G whereby the forward ends of the beams are movedvlaterally simultaneously with the rear ends thereof when the pole andtransverse slidable member are moved. The latter means preferablycomprises an arch l which is suspended from the pole and has outwardlyextending ends 41 suitably con- 43 in the pole. The means for connectingthe outwardly extending ends of the arch I with the forward ends of thebeams preferably comprise sleeves 44 having hollow projections 45secured by bolts 45 for pivotal movement in yokes 452 fixed on theforward ends of the beams H. On the angles of the arch I adjacent thesleeve 44 are elbow clamps 46, each of which has a forwardly projectingarm 47 having an eye at the end thereof. Each of the clamps 46,furthermore, has a rearwardly projecting lug 48.

It will be noted that when the pole is swung to the right or left itcarries the arch I bodily with it thereby correspondingly moving theforward ends of the beams H, H. In order that the arch may beeffectively supported and at the same time be freely movabletransversely of the implement, it is preferred to provide links 50, 50which extend rearward and upward from the arch and have their upper rearends pivoted at 51 to brackets 52 which are suitably secured to the sidemembers A and A2 of the frame,

Yand also to provideirods 53, 53 which extend upward from the arch andhave their upper ends pivoted to the ends of a transverse bar 54 whichis suitably secured to the members A A2 near the forward ends of thelatter. The forward ends of the links 50 and the lower ends of the rods53 are preferably connected to the arch I adjacent to the outwardly bentlower` ends 41 of the latter, the links 50 being connected to the lugs48 while the rods 53 are connected to the arms 47. It will now be seenthat when the implement is guided to dodge a stalk set out of line withthe rest of the row, or to follow a crooked row, or to avoid digging upthe crop in barring oil", the beams H are simultaneously moved bodilytransversely of the implement automatically by their describedconnection with the guiding mechanism.

In practice, means should be provided whereby the beams may be initiallyset in any one of a different number of selected angles. For the purposeset forth, the arms 39 which connect the ends of the transverse slidablemember E with the beams H are adjustable longitudinally of said member,being preferably carried by brackets K (see Fig. 4,) each of which has achanneled upper end portion which embraces the adjacent side of themember E, the latter preferably comprising two longitudinal spaced bars61, 61

having appropriate stiffening elements 62 at their ends. The spacing vofthe said bars 61 from each other provides a longitudinal opening in themember E which allows for the adjustment and guiding of the brackets 'YK. -Each bracket K also has a depending sleeve 63 in which theupper endof the arm 39 is secured (preferably adjustably) by suitable means, asthe set screw 64, and each bracket further has an upwardly extendingportion 65. A second bracket, L, mounted between the brackets K andwithin the space between the bars 61 of the member E carries a wheel 66having a shaft 67 with right and left threaded ends, the said ends ofthe shaft being threaded through trunnions 68 which are pivoted in theportion of the brackets K. The bracket L is secured to the member E asshown at 69. Hence, when the hand wheel 66 is turned the brackets K arecaused to slide so as to approach or recede from each other, thedepending arms 39 bearing against the boxes 40 and correspondinglyadjusting the rear ends of the beams H toward or away from each other,said beams turning pivotally on the vvertical axes 45 at their frontends. This adjusts the gangs toward and away from each other. Thebracket L preferably has a depending portion 70 which carries aprojection forming the element 37 hereinbefore referred to upon whichthe rear end of the pole G is pivoted, the said pole preferably having arearwardly extending strap 71 to engage said element 37, as shown inFig. 4.

The beams H, as usual, are preferably provided with means for adjustingthem pivotally on horizontal axes and holding them at various selectedheights. The means for this purpose may desirably comprise hand levers Mhaving latches 72, the said latches coperating with segments 73 suitablysecured to the frame of the implement. The forward ends of the handlevers M are connected with the beams H, respectively, nea-r the frontends of the latter, by rods 74 whose lower ends are pivoted to the beamsH at 75, the said rods having sliding connection intermediate of theirends with the forward ends of the levers M and being provided withsprings 76 which operate to hold the gangs yieldably to their work.

In practice, it is preferred that the forward ends of the levers M beprovided with yokes 77 carrying trunnions 78 projecting from collars 79through which the rods 74 extend loosely, the portions of the rods abovethe collars also extending through springs 80 which are arranged betweensaid collars and adjustable abutments 81 secured to 'the lower ends ofthe rods 74. The springs 76, have their upper ends bearing against theundersides of the collars 7 9 and their ,lower ends engage adjustableabutments 82 secured to the lower ends of the rods It will be understoodthat the springs 76 hold the gangs yieldably to their work while thesprings 80 coperatc with the rods 74 in forming a spring suspension forthe beams II which relieve the gangs from shock due to the passage ofthe wheels movement from the levers Ii to the rods 7SV in lifting thegangs. It will be noted that in the pivotal adjustment of the beams H,

to different heights the sleeves -li turn with the forward ends of thebeams, upon the outwardly extending portions ll of the arch I.
